London filmmakers Brian Fairbairn and Karl Eccleston have released a quirky, explicit anthropological music video about gay culture in 1970s San Francisco. The short film does not hold back, exploring hanky codes, earrings, fisting, urination, scat and more, all in the style of a 1970s sociological film.

It’s more or less a film adaptation of Hal Fischer’s 1977 study, set to music—a fun little pop number titled “House of Air.”
